  • Method of manufacturing tire product
    Patent number: 10800118
    Abstract: A method of manufacturing a tire product comprising: a step of preparing a core-assembly 4 of a rigid core 2 and a rubber member 3 formed on the rigid core 2, wherein the rigid core 2 is attached to a spindle device 7, and the rubber member 3 is to be vulcanization-molded, and constitutes all or a portion of a green tire, a step of conveying the core-assembly 4 from the spindle device 7 into a mold 50, and a step of vulcanization-molding the rubber member 3 on the rigid core 2 in the mold 50. The conveying of the core-assembly includes obtaining the weight of the rubber member 3 included in the core-assembly 4.
